Maximum runtime | 60 s | Max. memory usage | 250 MiB |
Function signature | resistance(band_colors) |
Write a function that accepts the input as function parameters and returns the correct output. Make sure to read the description above to produce the correct output in the correct format and use the correct function signature so we can run your code. A good first step is to try reproducing the example(s). Your code must not take longer than the maximum runtime to run and must not use more memory than the allowed limit.

Notes
- Since $1\;\Omega$ is a very small resistance, it's more common to express resistance in kilohms ($1\;\text{k}\Omega = 1,000\;\Omega$), megaohms ($1\;\text{M}\Omega = 1,000,000\;\Omega$), or even gigaohms ($1\;\text{G}\Omega = 1,000,000,000\;\Omega$).
- Nowadays it's easier to use a multimeter to measure it's actual resistance value. Calculating a resistor's value and tolerance from the color bands used to be more commonplace in the past when multimeters weren't as widespread or cheap.
- If you need a very specific resistance you can chain resistors in series or parallel. Variable resistors also exist in the form of potentiometers and digital resistors.
